To get to the car park, head towards Dortan. At the traffic lights in the town centre, follow signs for Bourg-en-Bresse and take the first small street on the left. The car park is located behind the post office on Rue du 19 Mars 1962.
(S/E) From the car park, walk past the post office, then turn right into Rue du Colonel Romans Petit. After the Merdançon bridge, follow Rue Neuve to the right, then turn right up Rue de l'Étang for about 50 metres to take the path on the left (yellow markings).
At the end of the path, cross Rue de la Léchère to reach Rue Bellevue via Rue de Maissiat. Head right towards La Pierre-qui-Vire, then turn left 60 metres further on to take a small unnamed street that continues along an uphill path to Rue de Maissiat.
(1) Pass to the right of the mobile phone relay antenna and continue along the small path to find yourself once again on Rue de Maissiat. Continue in this direction until you reach the hamlet of Maissiat d'en bas
(2) At the round fountain carved out of a block of limestone, turn right towards La Pierre-qui-Vire, then immediately left, following the low stone walls to continue along the wide, shaded path that climbs steeply and leads to a reservoir.
(3) At the reservoir, at the Y-shaped crossroads in the bend, keep left to continue north-west. The path passes through a clearing in the forest: continue in this direction, following the posts indicating Pierre-qui-Vire (yellow markings). The steep path climbs to the right to reach the ridge.
(4) At Pierre-qui-Vire, turn right towards the viewpoint: 5 min round trip: be careful of the cliffs! Turn back.
(4) Continue right towards the south-west towards Emondeau. Continue downhill through the Bois du Chatelard, following the yellow markings.
(5) At the signpost located at the crossroads, continue straight ahead towards Maissiat (0.5 km) to the south-east.
(6) At Maissiat d'en haut, turn left twice to reach Chemin de la Montagne, which continues as Rue de Maissiat. Pass the bread oven and turn right at the intersection onto Rue du Chêne: a signpost indicates Cascade de la Combe.
(7) Keep left on the path towards the waterfall, walking alongside the housing estate on the first section, then through a wooded area on a downhill path.
(8) Cascade de la Combe: at the bottom of the path, turn right to reach the foot of this pretty waterfall (2 minutes there and back), then take the path that runs alongside the Ruisseau de Maissiat to the street of the same name. Continue straight ahead towards the relay antenna.
(1) Take the small path that descends to the right. Follow the yellow markings, passing through Rue de Maissiat, Rue Bellevue, Rue de l'Étang and finally Rue Neuve, to return to the car park behind the post office (S/E).
